This invention is concerned with improvements-in a multiple glass window panev structure of the type having a heat insulating. space. between the panes.

An object of the inventionis toprovidea window pane unitcomprising two. or more panes of glassmounted in a channel-like frame and pro.- vided with a sealing gasket having a rib portion spacing the panes from each other, which unit has incorporated therein. a. breather member extending through the sealing gasket and a breather path leading, from. said breather member to an outer surface of the unit for. venting the otherwise closedair. space between the-spaced panes of. glass.

It isv a more specifici object ofthe invention to provide awindow pane unit. having multiple panes of glass supported. in. spaced relation by a sealing. gasket which sealing: gasket has incorporated therein a section constituting a breather member and means cooperating with the breather section to provide a-breather path ex.- tending from the breather section. to an outer side of the unit.

It is another object of the invention. to provide a' window pane unit having multiple panes of glass supported in spaced relation. by' a sealing gasket which sealing gasket has incorporated therein a section constituting. a. breather member, and means including a. longitudinally ex:- tending groove in the sealing; gasket: cooperating with the breather section to provide an indirect breather path extending. from the breather section to an outer side of the unit.

It is a further object of the invention: to provide in a multi-pan'e sash unit av sealing and spacing gasket having incorporated therein. a needle-like breather member and cooperating means providing a. breather path leading. from the: otherwise closed air spacebetween the spacedpanes to outside of the unit.

These and other objects of the invention will; be apparent from a description of the preferred form thereof which is shown by way of illustration inthe accompanying drawings, wherein:

Fig. 1 is an elevation of a sash unit embodying the principles of the invention;

Fig. 2 is a perspective view to an enlarged scale of a corner portion of the unit illustrating the corner joint of the channel frame;

Fig. 3 is a section on. the line 3-3 of Fig. 1 to an enlarged scale;

Fig. 5 is a sectional view on the line 5--5 oi?v Fis- Fig. 6 isaperspective view of a. portionof the sealing. strip; 1

Fig. 7 is a perspective view of the breather member; and

Fig. 8 isasection transversely through a sealingstrip illustrating a modified form of breather member.

Referring to. Figs. 1. to 7 of. the drawings, the sash unit illustrated comprises a generally U- shaped frame. or edge encompassing member it formed. byconnectingv attheir corners the. four channeled sections ll, l2, [.3 and. I4.

The preferred. corner construction is particularly illustrated in Fig.2 which shows the corner joint betweenframe sections 12' and. [3. It comprises a projecting. lug or tongue [5' formed on the base portion I6 of the mitered corner of the section l2. and a projecting tongue I1 formed on the base portion [8 of the mitered corner of the section It. The tongue. [1 is provided with a slot [9 along the meeting line of the base portions It and I8 of the sections l2' and l3.which is of a size sufficient to snugly receive the tongue [5. The sections it and I3 are assembled in abutting relation with the tongue. I5 projecting through the slot l9 and the tongues I5 and H are then bent down fiat against the outside faces of the base portions [8 and it of the channel members l3 and 52, respectively. The connections at each corner of the. frame ID are identical.

Two panes. of glass 29. and 2| are positioned in the frame member In in spaced relation with their outside faces in engagement with inturned. edges 22 and 23 of the legs or flanges 24 and 25, respectively, of the frame member iii. The panes 2G and 21 are spaced from each other to provide an insulating air space 26 between their inside surfaces. They are held inspaced relation by a rib-like portion 2'! of a sealing gasket 28 which surrounds the lateral edges of the panes.

The sealing gasket" 28' is generally T-shaped provided with a generally fiat transversely extending top portion 29 and the rib-like leg or stem portion 21. The rib portion 2.? is provided with. outwardly sloping faces 33 and 3! and a lower generally concave face 32'. portion 2'"! is positioned between the glassy panes 2B and 21, the tapered leg-like formations and 34' formed by the tapered and curved cross section of the rib 2?. are compressed or moved to ward each other to bring a substantial portion of the tapered surfaces 3i and 3| into surface engagement with the inner surfaces of the glass panes 20 andv 2|, thus sealing and enclosing the, space between the panes. The. laterally extending side portions 35 and 36 of the top por- When the ribv tion 29 of the sealing gasket 28 are positioned between the base l3 and the lateral edges 31 and 38 of the panes 20 and 2!. The side portions 35 and 36 provide a seal between the edges 31 and 38 of the panes 2B and 2! and the frame Ii].

The sealing gasket 28 has incorporated in its length a relatively short breather member or block 39 (Fig. '7) which is of the same crosssectional configuration as the sealing gasket 28 and which is preferably formed of porous rubber of the type having minute passageways therethrough which are sufficient to permit passage of air. The breather member or block 39 is initially vulcanized in integral relation with the sealing gasket 28 and forms an integral portion thereof so that the sealing gasket completely surrounds the panes 25 and 2! on all four sides.

The sealing gasket 23 is provided with a longitudinal groove 40 which is located in the outer surface of the top portion 29 and which extends completely around the sealing gasket 28 except for the portion of the same which constitutes the breather member 39.

The frame H3 is provided with a transverse groove 4| on the inner face of the base portion l8 of the frame member I3, at a point spaced from the porous member 39 which when the sealing gasket 28 is arranged with its top portion 29 in contact with the base 18 provides a passageway from the groove 40 outwardly beyond the lateral portions 35 and 36 of the sealing gasket 28 and into communication with the space formed between the outer surfaces of the panes 29, 2|- and the inner surfaces of the legs 24, 25 of the frame member 3. One leg 24 of the frame is provided with an opening .2 at the edge for communication with. the outside atmosphere which opening may be conveniently formed by straightening a small portion of the turned-4n edge 22. By means of this construction air is permitted to pass from the air space 26 between the panes 20 and 2i through the breather block 39 into the groove 48 in the sealing gasket 28, along the groove all to the transverse groove M, along the groove M and through the openin 42 to the outside atmosphere, thus providing an indirect path for venting the space 26 and eliminating the formation of moisture due to unequal temperature conditions.

In Fig. 8 a modified. sealing gasket construction is illustrated. In this construction the sealing gasket is formed of solid rubber and is provided at one point with a hypodermic needle type of breather member 46. The breather member 44 extends through the gasket 43 from the top thereof and connects a longitudinal groove 45 in the top of the gasket 43 with the air space between the panes by a. minute passageway. The breather member 44 is located at a point spaced from the transverse groove which connects with the outlet opening.

A further modification consists of substituting for the transverse groove 4| in the frame of the preferred form, a transverse groove in the sealing gasket 21' to provide a transverse passageway connecting the longitudinal groove 49 with the space between the outer surface of the panes and the channels and thence through the opening 42 provided in the edge of the frame to the outside atmosphere.

While specific details of construction and materials have been referred to in describing the illustrated embodiments of the invention, it will be understood that other details of construction and other materials may be resorted to within the spirit of the invention.
